We went to the fair yesterday. You can read my husband's comments about it here.
For Conor and Emma, the highlight was getting to climb on a tank.

For me, the highlight was the cotton candy and funnel cake. (See extended entry for a funnel cake recipe.)
Funnel Cake
1 cup flour
3/4 cup milk
1 tsp. baking powder
1/8 tsp. salt
1 egg
powdered sugar or cinnamon sugar
vegetable oil for frying
1/2" spout funnel
Heat about 1" of oil in a 12" skillet to 375 degrees. Mix flour, milk, baking powder, salt, and egg with a fork. Hold finger over the spout of the funnel and pour 1/4 cup of batter into the funnel. Hold over hot oil, remove finger from spout, and let batter pour into the oil while moving the funnel in a 6" spiral pattern. Fry until golden brown, turning once. Drain well on paper towels and sprinkle with powdered sugar or cinnamon sugar. Repeat with the remaining batter. Serve hot.
